Free Mixtures Basic Skills Worksheets for grades 3–5. A clear mixture can still contain more than one substance. Mixling helps students explain dissolving, compare mixtures that settle, and choose separation methods using particle size and magnetic behavior.

This six-page packet includes two teacher-guide pages, three student worksheets and an 18-point answer key. Students practice 16 tasks: matching, fill-in, classifying cases, multiple choice and explaining evidence. Print the three student pages; keep the guide and key for instruction. No kit or purchase is required.
Meet Mixling
Gemlings teach science through their personalities and home realms. Mixling guides learners in Mixmaster Bazaar. The character’s teaching note introduces the science mission, and the final encouragement recognizes the student’s learning.
Science topics
- What Mixtures Are
- Comparing Mixtures
- Dissolving & Solutions
- Separating by Size & State
- Separating by Magnetism
- Planning a Separation
Simple classroom use
Allow about 20–30 minutes or split the work across lessons. Model the toolbox words and read the case cards aloud when helpful. Students match clues, complete ideas, classify cases and explain evidence. Use the answer key to discuss corrections; accept accurate explanations in a child’s own words. Tasks 1–14 earn one point each and tasks 15–16 earn up to two each.
Give partners a written mixture such as dry iron pieces, pebbles, and sand. Ask them to choose and order separation steps, naming the property used each time. Add dissolved salt water as a contrast that an ordinary filter cannot solve.
A science teaching tip
Dissolving is not disappearing. Ordinary filtration does not remove dissolved salt, and magnets do not attract every metal strongly. A separation plan should identify what is recovered and what the method leaves behind.
Train, refresh, then assess
Start with free subject vocabulary training or the free subject reading resource. After worksheet practice, open the subject Adventure page to watch the Gemling video for learning or a refresh, then take the free Online Adventure assessment. The worksheet score is classroom practice, separate from that assessment.
Optional hands-on discovery
Dig Kits can extend Discover–Identify–Collect: uncover specimens, identify them using observations and available specimen/trading cards, and organize a collection. Free worksheets and Online Adventures stand on their own. Teachers may purchase available kits, explore the Free Dig Kits campaign, or ask about possible PTA/PTO funding. Signup does not automatically guarantee free kits; current funding and fulfillment conditions apply. PTA/PTO funding is not guaranteed.
